Yeah, I have a huge personal fascination with the TH movement and am looking at ways to make it work for me, but in terms of an investment in real estate, just always be aware that anything recognized as an "outlier" has lower liquidity.
My mom, god bless her, was an agent when I was a kid and has helped steer my analysis and buying decisions as I later became a homeowner, investor, and agent myself. Thanks to her, nothing excites me more than a boring, cookie-cutter, 1100-1500SF, 3BR, 2BA house, stuck in the middle of a huge tract of identical or at least similar homes. ;)
That said, I'd still consider this if it were near me. Three of my prospects right now are ~$40k SFHs rented for $595... slightly cheaper but bigger and older, with more maintenance costs expected.
The two questions I'd be most interested in answering in detail, and with high precision, are the likely rent (are there any legitimate comps nearby? Is this the only TH in the neighborhood?) and the likely upkeep. This home could have a real advantage in terms of maintenance costs because there's just less stuff to break. Even when major components start hitting EOL, you might run less than the 50% rule of thumb for total costs, based on that. But it really bears detailed research, and with TH being relatively new there may not be a lot of historical data. And some builders might be kicking out poor-quality units too, negating the benefit.
But I ramble... does this make sense?
